Symptoms

In the Configuration utility, when creating or editing a LTM policy, the ASM control option may be missing from the rule screen.

Impact

ASM cannot be enabled in LTM policies using the Configuration utility.

Conditions

Whether the ASM control option is present or missing purely depends on the license installed on the system. The system incorrectly reports certain licensed modules to the Configuration utility, which fails to parse them and ultimately to display the ASM control option. If you wish to determine whether you are affected by this issue, SSH to the advanced shell of the BIG-IP system and run this command: # grep -E '^active module : [^|]*\|[^|]*$' /config/bigip.license If any output is returned, then you are affected by this issue.

Workaround

Use the TMSH utility to enable ASM in LTM policies.

Fix Information

ASM can now be enabled in LTM policies using the Configuration utility regardless of the license installed on the system.
